1. Artificial hatching, the birth plate is removed and placed in a special hatching bucket. The hatching rate is high and it is easy to manage. The broodstock can recover well. The method is simple, just heat the water that has been left out for 3 days to the temperature of the breeding tank and put the birthing board in. When placing the eggs on the plate, place the eggs diagonally upward and turn the production plate up and down to help hatch smoothly. The hatching bucket should contain 10-15 liters of water and a water depth of 20-25 centimeters.

2. The eggs hatch in 45-50 hours. After hatching, they hang on the birthing board for 5 days and do not swim off the board until the 7th day. There will be some dead eggs and small fish that fell from the board, and they will be removed after the small fish leave the board. During the incubation period, do not change the water, control the temperature, and add 4-5 hours of light every day.

3. The small fish swim away from the board for 5-8 hours before feeding the open bait, feeding migratory water or brine shrimp larvae.

4. When changing the water of small fish, wait until the third day of feeding for the first time. Control the water change amount at 10%-15%. First, carefully suck up the yolk water excreted by the small fish. Then add new water that has been dried and has the same temperature. The water should be added gently, slowly and slowly, and the small fish must not be washed away. From now on, change it every day or two.
